Actively controllable stent, stent graft, heart valve and method of controlling same

A method for implanting a prosthetic heart valve, comprising:

• advancing a prosthetic heart valve into a patient's vasculature with a delivery apparatus;
• positioning the prosthetic heart valve at an implantation location;
• expanding the prosthetic heart valve from a contracted state to an expanded state with the delivery apparatus;
• and
• displaying a diameter of the prosthetic heart valve on a display during the act of expanding;
• displaying a radial force imparted to native heart valve tissue by the prosthetic heart valve on the display during the act of expanding;
• and
• providing a warning when the radial force is less than a force necessary to prevent embolization of the prosthetic heart valve.

A delivery apparatus, comprising:

• a handle portion having an actuation mechanism, wherein the actuation mechanism includes a motor and one or more actuators;
• and
• at least one rotatable drive shaft having a proximal end portion and a distal end portion, wherein the proximal end portion is coupled to the motor, and the distal end portion is configured to be releasably coupled to a prosthetic heart valve,
• wherein the actuation mechanism includes electronic control circuitry configured to expand the prosthetic heart valve from a fully contracted diameter to a pre-defined diameter and to automatically stop expansion at the pre-defined diameter based on a first actuation by a user.
